The Simplified Chinese Windows 10 Single Language Edition actually allows to use English from get go, nice👍.

Since you can only recover or reset with Windows's built-in tools, there's no such a thing of recovery media. You can use GParted Live to image the whole drive (like I did) remember to disable Secure Boot in BIOS (which you can push both volume up and power button while booting and you will see the boot menu shortly. This only works when Windows fast boot is disabled, aka, shutdown with shift key pressed). You also need a USB hub and external keyboard and mouse (without Windows, Halo Keyboard will not work) as well as a flash drive. Charge fully before entering GParted Live since you cannot charge with power back-feed from the hub. In most cases an external monitor is required, due to it will display broken image when enters X (but works fine with an external monitor, how strange😵). The storage is eMMC-based, so there's no u-boot, special partition table, etc. You may dd the whole thing.

The first thing after you boot up Windows is to remove Lenovo Paper from program and features. Or every time you hit volume button, OneNote pops out.

If you are not a fan of start up apps (especially the sound card control app, which cannot be disabled or quit normally) use Task Manager or CCleaner to kill RtkNGui64.exe. Not a fan of Dolby effect (it's terrible anyway)? Kill RtI2SBgProc64.exe as well (along with Dolby-related apps in program and features). Other stuff might be helpful, leave them as is.

If you want to tweak the pen, you can use Wacom Feel driver. Although it will take over the pen from Windows Ink so don't use this driver if you are not plan to use with Photoshop.

All drivers are available at Lenovo support website. The Intel Chipset package contains countless BS. Sorry I don't know how to install the drivers the right way, since I have never succeed😂

If you just want to update your current drivers, don't trust those drivers that claim to be updated before March 2017 (which IS every single driver) because this product does not receive ANY driver update EVER (except BIOS).

If you want to update BIOS, remember to disable BitLocker. Apparently there are Yoga Books manufactured with BitLocker enabled by default. Without a proper recovery key, you WILL NOT retrieve any data from those encrypted partitions after BIOS update.

I still failed to find a way to enable FnLk by default after boot 😭 which is really inconvenient. This is a Windows PC, not a Mac. Without function keys by default is not acceptable.

I complained about the touchpad here, but recently I discovered that Goodix (which manufactures the touch module in Yoga Book) drivers comes with several configurations in registry 😎 Except those can be tweaked with Halo Keyboard app (includes button sound/vibration and backlight timeout/brightness), you can also change several other settings registry address HKLM\SYSTEM\CurrentControlSet\Services\GoodixTouchDriver (remember to backup registry first, all values shown here are in decimal, not hexadecimal):

You can adjust the range of touchpad with TP_TOP, TP_BOTTOM, TP_LEFT and TP_RIGHT. I tried to change the left and right boundary (which extends touchpad to palmrest) but failed. It seems you can only shrink the range but not enlarge. Firmware limitation? (or maybe hardware limitation)

It seems the driver divides touchpad into 4 sections (labelled as A, B, D and E). I believe A and B are for touchpad buttons, while D and E is explained here:

Section D is the right click area INSIDE the touchpad (not the button to the right). That's correct, you can use the button to right click but also right click with the fourth quadrant of the trackpad (who designed the driver?! 😤). If you change following values the area will be disabled:

TP_D_TOP = 0

TP_D_LEFT = 1276

Section E is the activation area of touchpad (page 6 user guide, although the user guide is not entirely right, either). Usually after you finish typing, the touchpad is disabled unless you start the stroke from the activation area, which prevents accidental touches. But in real life that is a textbook-level design failure. You can tweak the value of section E as follow to disable this function:

TP_E_LEFT = 508

TP_E_TOP = 357

TP_E_RIGHT = 1276

TP_E_BOTTOM = 0

As of how to enable two-finger right click and drag lock, sorry I gave up. There are other values looks like can be used to enable FnLk by default, but it doesn't work as expected.

What makes it worse is that all those settings can be easily adjusted in Android version, as well as strength of vibration. Yeah. The Windows Yoga Book is a disaster, period 😩

The screen and touch will turn on when you hit the power button WITH the lid closed (WTF!? so it's a tablet after all, huh?) Sometime the Yoga Book stop to respond after a long period of sleep. There's a easy fix: disable Windows hibernation and fast boot, and the chance of hang will decrease significantly.
